The optional low-pressure gradient unit can be incorporated in the LC-20AD/20AT, enabling gradient elution in a compact space with a small void volume. Automatic matching adjustment of the solenoid valve and pump gives concentration accuracies of ±1.0%.
A new type of plunger made with a technique that reflects consideration of the material structure and a precise plunger-holding mechanism help to increase the service life of plunger seals and enable stable solvent delivery over long periods.
